Other info. - This species of Galium is very easy to distinguish from our native species because it has distinctive whorls of 8-10 leaves per node and showy terminal inflorescences. This species is fast growing and could easily become established if it escapes cultivation. The plant contains coumarins and gives off a distinctive "hay" scent when cut, hence the species name.
